Which would be a better way to load data via ajax
- by Mike
I am using google maps and returning html/lat/long from my MySQL database
Currently
A user picks a business category e.g; "Video Production".
an ajax call is sent to a CodeIgniter controller
the Controller then queries the db, and returns the following data via JSON
Lat/Long of the marker
HTML for the popup window
this is approximately 34 rows in the database across two tables per business
the ajax call receives this data and then plots the marker along with the html onto the map
The data that is returned from the controller is one big json object... This is done for all businesses that exist in the Video Production category (currently approx 40 businesses). As you can see, pulling this data for multiple categories (100s of businesses) can get very very taxing on the server.
My question is
Would it be more beneficial to modify the process flow as such:
a user picks a business category e.g; "Video Production".
an ajax call is sent to a CodeIgniter controller
the controller then queries the database for the location base information
lat/long
level (used to change marker icon color)
This would be a single row per business with several columns
the ajax call receives this data and then plots the marker on the map
when the user clicks a marker an ajax call is sent to a CodeIgniter Controller
the controller queries the database for the HTML and additional data based on business_id
and if not, what are some better suggestions to this problem?
In summary this means rather than including the HTML and additional data along for each business, only submitting minimal location information and then re-query for that information when each business marker is clicked.
Potential Downsides
longer load times when a user clicks a marker icon
more code??
more queries to the database
